About
In the world of cryptocurrency, We are bombarded with many different kinds of wallets to use which does not creates a good sense for newbies and even the old ones. We want to make transfer easy for people that have yet to onboard or has their crypto-wallet ready. At least say, they are not being pressured to create a wallet on the go while still retaining ownership of the fund that was transferred to them. The thought of using a smart contract and linking the Twitter handle(username) to a wallet address helps to make the transfer easy. At the same time, we also get the benefit of transferring funds using a recognizable name.
How it's made
This project uses Hedera smart contract. More specifically, we use the Strato library to communicate with the smart contract. We use Twitter API which to validate the user and send a notification to them when there is a fund transferred to their name. On the main page, we have separated them into 2 core logic. `\wallet` page and `\twitter` page. + `\wallet` page need to connect via Hashpack wallet before proceed. + on the page, user get to transfer via Twitter or see their transfer list. + `\twitter` page need to connect via Sign In with Twitter. + on the page, it guide user to setup the wallet and update their wallet to the oracle smart contract. + the user also get to see the list of fund that is transferred to them via this service. + the used of MongoDB is to store the transaction for query. However, the source of truth is will be on the chain itself.
